    A wide range of zero-dimensional powders can be converted into versatile, high-performance one-dimensional micro-/nanofibres by using two-dimensional cellulose sheets as a mediator, preserving the particles’ nanostructural features and acting as building blocks for complex geometric shapes to satisfy application requirements.

    The room-temperature self-healing behaviour of a nanotwinned diamond composite is quantitatively evaluated and found to stem from both the formation of nanoscale diamond osteoblasts and the atomic interaction transition from repulsion to attraction.

    In spite of their promise, practical applications of high-temperature cuprate superconductors have been hard to come by. The development of a method to fabricate round wires of the cuprate system Bi-2212 may begin to change this.

    Gathering information on the evolution of small cracks in ceramic matrix composites used in hostile environments such as in gas turbines and hypersonic flights has been a challenge. It is now shown that sequences of microcrack damage in ceramic composites under load at temperatures up to 1,750 °C can be fully resolved with the use of in situ synchrotron X-ray computed microtomography.

    Implantable neural microelectrodes are critical to neuroscience research and emerging clinical applications including brain-controlled prostheses. A composite electrode consisting of a carbon fibre core, an insulating polymer coating and a polythiophene-based recording pad has now been developed that shows reduced chronic reactive tissue response in rats compared with existing architectures, owing to its smaller size and improved mechanical compliance with brain tissue.

    Magnetoelectric composite materials are of interest for sensitive magnetic-field sensors. The realization of a magnetoelectric composite that does not require an applied external magnetic field, but instead relies on internal bias via exchange coupling, promises sensitive sensors even for small magnetic fields.

    The fabrication of composite microfibres with tunable topography and chemical composition is now possible with a microfluidic method that mimics the fibre-spinning process of spiders. The method allows for the synthesis of a variety of structurally and spatially coded fibres for multiple applications, such as directional water harvesting and the co-culture of encapsulated cells.

    Although crumpled sheets have large resistance to compression, little is known about the dynamical evolution of their three-dimensional spatial configurations. The formation of a network of ridges and vertices into which the energy is localized is now observed during dynamic crumpling under isotropic confinement.

    The detection of acoustic signals is of relevance for a range of practical applications, for example in medical diagnostics. However, in contrast to the rectification of electric current in diodes, acoustic rectification has not yet been achieved. The first experimental demonstration of an acoustic rectifier therefore promises significant impact for practical applications.

    A biomedical application of a nanoconjugate is now shown in vivo. Sealed carbon nanotubes filled with a radionuclide are functionalized with carbohydrate molecules without prompting cargo release. The stability and biocompatibility of the capsule together with the radioactive payload enables in vivo imaging of the system and delivery of a high-density radiodose.
